A common question is "Can I use maps from <> or scanned images in BackCountry Navigator"
This tool will allow you to create new maps from your own data.
Note that not all formats are practical to extract data from. Some are closed and proprietary. Garmin .img format is one that is often asked about, for which we don't know of a solution right now.
PLEASE NOTE: The format recommended is "RMAPS (SQLite)" or "BackCountry Navigator(SQlite)". This is the easiest to use currently as it is a single file.
A related question is often 'Can I use my desktop to download?'

In the latest version of Mobac, RMaps SQLite format and BackCountry Navigator format are identical.
When you have created a mobile atlas, you can place it on your device storage. Choose "More Map Sources" from the Layers menu and choose "Use Mobile Atlas and browse to the file you created.
